    Electrical fire cannot be safely out out by dousing them with water. However, fire extinguishers that spray solid carbon dioxide on the fire work very effectively. This method works because carbon dioxide. 

    • Displaces the oxygen
    • Fenders the fire’s fuel non- flammable
    • Forms water vapor
    • Blow the fire out with strong wind currents

    What is a Protein made out of?

    • RNA

    • Codons

    • Amino Acids

    • Lipids

    Correct Answer
    A. Amino Acids
    Explanation
    Proteins are made up of amino acids. Amino acids are organic compounds that contain both an amino group and a carboxyl group. They are the building blocks of proteins and are linked together through peptide bonds to form long chains. These chains then fold and interact to create the unique structure and function of each protein. RNA and codons are involved in the process of protein synthesis, but they are not the actual components that make up proteins. Lipids, on the other hand, are a different type of biomolecule and are not involved in protein formation.

    Which of the following is a function of the nervous system? 

    • Releasing ATP into contracting muscles tissues

    • Signaling muscle tissues to contract

    • Producing lactic acid in fatigued muscles

    • Increasing cellular respiration in muscle tissue

    Correct Answer
    A. Signaling muscle tissues to contract
    Explanation
    The correct answer is signaling muscle tissues to contract. The nervous system plays a crucial role in coordinating and controlling the body's movements. It sends electrical signals, known as nerve impulses, to muscle tissues, which then contract in response to these signals. This allows for voluntary and involuntary movements, such as walking or digesting food. The other options mentioned, such as releasing ATP, producing lactic acid, and increasing cellular respiration, are not specific functions of the nervous system.

    The Moon is very hot  on the side facing the sun & very cold on the dark side. This extreme temperature difference is primarily due to the Moon’s:

    • Mineral composition

    • Thin atmosphere

    • Reflective rock

    • Lack of volcanic activity

    Correct Answer
    A. Thin atmosphere
    Explanation
    The Moon's thin atmosphere is the primary reason for the extreme temperature difference between its sun-facing side and dark side. Unlike the Earth, which has a thick atmosphere that helps distribute heat, the Moon's thin atmosphere cannot effectively regulate temperature. As a result, the sun-facing side of the Moon becomes very hot due to direct exposure to the sun's rays, while the dark side remains very cold as it lacks the atmosphere to trap and retain heat. The Moon's mineral composition, reflective rock, and lack of volcanic activity do not play a significant role in causing the extreme temperature difference.

    What is the first phase of the cell cycle?

    • Prophase

    • Interphase

    • Metaphase

    • Anaphase

    Correct Answer
    A. Prophase
    Explanation
    Prophase is the correct answer because it is the first phase of the cell cycle. During prophase, the genetic material inside the nucleus condenses and becomes visible as chromosomes. The nuclear envelope also starts to break down, and the spindle fibers begin to form. This phase prepares the cell for division by ensuring that the genetic material is properly organized and ready to be separated into two daughter cells.

    At which point does a roller coaster have the most kinetic energy?

    • On the top of the biggest hill

    • Bottom of the biggest hill

    • Top of the smallest hill

    • Bottom of the smallest hill

    Correct Answer
    A. Bottom of the biggest hill
    Explanation
    The roller coaster has the most kinetic energy at the bottom of the biggest hill. This is because kinetic energy is directly proportional to the square of the velocity of an object. As the roller coaster descends from the top of the hill, it gains speed and therefore its velocity increases. Since kinetic energy is dependent on velocity, the roller coaster will have the most kinetic energy at the point where it has the highest velocity, which is at the bottom of the biggest hill.

    Aerobic Cellular Respiration goes through what steps?

    • Glycolysis, Krebs cycle, Electron Transport Chain

    • Electron Transport Chain, NAD+ Cycle, gel electrophoresis

    • Glycolysis, Calvin Cycle, Chordata

    • Moe, Larry, Curly

    Correct Answer
    A. Glycolysis, Krebs cycle, Electron Transport Chain
    Explanation
    Aerobic cellular respiration is a process in which glucose is broken down to produce energy. The first step is glycolysis, where glucose is converted into pyruvate. The pyruvate then enters the Krebs cycle, also known as the citric acid cycle, where it is further broken down and produces molecules that carry energy. Finally, the energy-carrying molecules produced in the Krebs cycle enter the electron transport chain, where they are used to generate ATP, the main energy currency of cells. Therefore, the correct answer is glycolysis, Krebs cycle, and electron transport chain.

    How old is the earth?

    • 6,000 years old

    • 4 million years old

    • 4.5 million years old

    • 4.6 million years old

    Correct Answer
    A. 4.5 million years old
    Explanation
    The age of the Earth is estimated to be around 4.5 million years old. This estimation is based on various scientific methods and evidence, such as radiometric dating of rocks and minerals, the study of fossils, and the analysis of the Earth's geological processes. These methods have provided consistent results and support the understanding that the Earth has been evolving and changing over a long period of time.

    What is the name of the outer edge of a cell?

    • Shell

    • Plasma Membrane

    • Nucleus

    • Cell Wall

    Correct Answer
    A. Plasma Membrane
    Explanation
    The correct answer is Plasma Membrane. The plasma membrane, also known as the cell membrane, is a thin, semi-permeable barrier that surrounds the cell and separates the interior of the cell from its external environment. It controls the movement of substances in and out of the cell, allowing nutrients to enter and waste products to exit. The plasma membrane is essential for maintaining the integrity and functionality of the cell.
